This is just an incompatibility note. The avast service is running, but more than half of the time when it comes to starting up the machine,the avast gui does not load next to the clock in the taskbar. The gui can be started manually however, and everything seems to work ok. I have binisoft WFC, crystaldiskinfo and winpatrol on startup. The avast service is not prohibited by any program. I have only installed the primary scanner (file shield). I suspect it's an WFC or windows firewall issue
